Ensure that all latches and hinges are in the correct operating condition.3. Check the power cords for damage.4. Check the external signal cables for damage.5. Check the cover for sharp edges, damage, or alterations that expose the internal

parts of the device.6. Correct any problems that you find.

Internal device checksEnsure that you complete an internal device check before you install or serviceSAN Volume Controller.

About this task

To conduct the internal device check, perform the following steps:

Procedure1. Check for any non-IBM changes that might have been made to the device. If

any are present, obtain the “Non-IBM Alteration Attachment Survey,” formnumber R009, from the IBM branch office. Complete the form and return it tothe branch office.

2. Check the condition of the inside of the device for any metal or othercontaminants, or any indications of water, other fluid, fire, or smoke damage.

3. Check for any obvious mechanical problems, such as loose components.4. Check any exposed cables and connectors for wear, cracks, or pinching.

Safety and environmental notices xxi

About this task

To test the grounding of a SAN Volume Controller node: Follow the steps for theSAN Volume Controller configuration that you are using. Before you start, confirmthat you know the SAN Volume Controller model type. Determine the location ofthe signal cables that are attached to the SAN Volume Controller.

When you are asked to test the grounding continuity, use your local procedures toinitiate the test. The test is successful if the measured resistance is 0.1 ohm or less.

Attention: Some electrical circuits can be damaged if the external signal cablesare present at the SAN Volume Controller while it is undergoing a grounding test.

Procedure1. Ensure that the SAN Volume Controller node is powered off. See MAP 5350:

Powering off a SAN Volume Controller node in the IBM SAN Volume ControllerTroubleshooting Guide.

2. Disconnect all signal cables from the SAN Volume Controller node, whichincludes the following cables:v The Fibre Channel cablesv The Ethernet cable or cables

3. Disconnect the power cable from the site power-distribution unit.4. Disconnect both input power leads from the site power distribution units.5. Test the grounding continuity between a conductive area on the SAN Volume

Controller frame and the ground pin on the plug of each input-power cable.6. After you have completed testing the grounding continuity, initiate one of the

following procedures, depending on the outcome of the test.v If the test is successful, reconnect any cables that were removed, and power

on any SAN Volume Controller nodes that were powered off.v If the test was not successful, ensure that all cables are securely connected. If

the test still fails, test the individual system components. Before you test theindividual components, remove all cables from the components. If anycomponent test fails, replace the component. After each component has beentested and the failing ones have been replaced, repeat the complete systemtest by returning to step 1.

v Test the SAN Volume Controller node, from the frame to the ground pin ofthe input power receptacle.

Emergency power-off shutdownThe SAN Volume Controller supports emergency power-off (EPO) shutdowns.

Handling static-sensitive devicesEnsure that you understand how to handle devices that are sensitive to staticelectricity.

Attention: Static electricity can damage electronic devices and your system. Toavoid damage, keep static-sensitive devices in their static-protective bags until youare ready to install them.

To reduce the possibility of electrostatic discharge, observe the followingprecautions:

xxii SAN Volume Controller: Model 2145-DH8 Hardware Installation Guide

v Limit your movement. Movement can cause static electricity to build up aroundyou.

v Handle the device carefully, holding it by its edges or frame.v Do not touch solder joints, pins, or exposed printed circuitry.v Do not leave the device where others can handle and possibly damage the

device.v While the device is still in its antistatic bag, touch it to an unpainted metal part

of the system unit for at least two seconds. (This action removes static electricityfrom the package and from your body.)

v Remove the device from its package and install it directly into your SANVolume Controller, without putting it down. If it is necessary to put the devicedown, place it onto its static-protective bag. (If your device is an adapter, place itcomponent-side up.) Do not place the device onto the cover of the SAN VolumeController or onto a metal table.

v Take additional care when you handle devices during cold weather. Indoorhumidity tends to decrease in cold weather, causing an increase in staticelectricity.

xxxiv SAN Volume Controller: Model 2145-DH8 Hardware Installation Guide


Chapter 1. Preparing to install the SAN Volume Controller

Before installing the SAN Volume Controller, you must meet the hardware,software, and environmental requirements (including a suitable rack cabinetphysical location). Learning about the controls, indicators, operator-informationpanel, and connectors will prepare you for the installation procedures.

The SAN Volume Controller combines software and hardware into acomprehensive, modular appliance that uses symmetric virtualization.

Symmetric virtualization is achieved by creating a pool of managed disks (MDisks)from the attached storage systems. Those storage systems are then mapped to a setof volumes for use by attached host systems. System administrators can view andaccess a common pool of storage on the storage area network (SAN). Thisfunctionality helps administrators to use storage resources more efficiently andprovides a common base for advanced functions.

Each SAN Volume Controller node is an individual server in a SAN VolumeController clustered system on which the SAN Volume Controller software runs.

The nodes are always installed in pairs; a minimum of one pair and a maximum offour pairs of nodes constitute a system. Each pair of nodes is known as an I/Ogroup.

SAN Volume Controller operating environmentTo use the system, you must meet the minimum hardware and softwarerequirements and ensure that other operating environment criteria are met.

Minimum requirements

You must set up your SAN Volume Controller operating environment according tothe following requirements:v At least one pair of SAN Volume Controller nodesv A 19-inch rack-mounted enclosure

SAN Volume Controller 2145-DH8 node features

The SAN Volume Controller 2145-DH8 contains:v At least one Fibre Channel adapter or one 10 Gbps Ethernet adapterv Optional second and third Fibre Channel adaptersv 32 GB memory per processorv One or two eight-core processorsv Dual redundant power suppliesv Up to two SAN Volume Controller expansion enclosures to house optional flash

About this task

CAUTION:

v To lift and install the enclosure into the rack requires at least two people.

v Load the rack from the bottom up to ensure rack stability. Empty the rackfrom the top down.

Procedure

To install an enclosure, complete the following steps.1. Align the enclosure with the front of the rack cabinet.2. Carefully slide the enclosure into the rack along the rails until the enclosure is

fully inserted (see Figure 49).

Note: The rails are not designed to hold an enclosure that is partially inserted.The enclosure must always be in a fully inserted position.

3. On either side of the drive assemblies, remove the enclosure end caps bygrasping the handle and pulling the bottom of the end cap free, then clearingthe tab on the top of the enclosure.

4. Secure the enclosure with a screw in the rack mounting screw hole.5. Reinstall the left and right end caps as shown in Figure 49. The left end cap has

indicator windows that align with the status LEDs (light-emitting diodes) onthe edge of the enclosure.a. Ensure that the serial number of the end cap matches the serial number on

the rear of the enclosure.b. Fit the slot on the top of the end cap over the tab on the chassis flange.c. Rotate the end cap down until it snaps into place.

Figure 49. Inserting the enclosure


d. Ensure that the inside surface of the end cap is flush with the chassis.

Connecting the optional expansion enclosuresAfter you install the expansion enclosures into the rack, you must connect them toeach node.

About this task

This task applies if you are installing one or more expansion enclosures. Each pairof nodes in the system can manage two expansion enclosures. Each expansionenclosure is attached through the outbound SAS ports on the nodes, connecting tothe inbound port of the expansion enclosure.

Note: When you insert SAS cables, ensure that the connector is oriented correctly.v When connecting to a expansion enclosure, the blue pull tab must be below the

cable (▌1▐ in Figure 50).v When connecting to a node, the blue pull tab must be above the connector (▌2▐

in Figure 50).v Insert the connector gently until it clicks into place. If you feel resistance, the

connector is probably oriented the wrong way. Do not force it.v When inserted correctly, the connector can be removed only by pulling the tab.

▌1▐ Correct orientation for expansion enclosure▌2▐ Correct orientation for node

Be aware of the following guidelines when you begin to attach the cables to theSAS ports.v No more than one expansion enclosure can be chained to either of the two SAS

ports on the node (ports 1 and 3). This configuration creates two separate chainsof one enclosure each. Use Figure 51 on page 48 to install the enclosures.

Note: Figure 51 on page 48 is provided to show what SAS ports on each devicethe SAS cables get connected to. It does not imply or represent the preciseracking order for the devices in a cabinet/rack.

v No cable can be connected between a port on a left canister and a port on aright canister of the expansion enclosures.

v Ensure that cables are installed in an orderly way to reduce the risk of cabledamage when replaceable units are removed or inserted.

1 2svc00868

Figure 50. SAS cable connector orientation


v SAS cables must be routed through the cable management arms to avoid the riskof the nodes getting disconnected from their flash drive arrays or the SAS cablesgetting damaged if the node is slid out on its rails while attached to theenclosure.

v Arrange your cables to provide access to the following components:– Ethernet ports, including the technician port. The technician port is used for

initial setup of the system by directly attaching to a personal computer. It canalso be used to complete service actions for the system.

– USB ports. USB ports can be used to initialize the system or to performservice-related tasks by using a USB flash drive that contains executable filesfor initializing the system.

– Fibre Channel and Fibre Channel over Ethernet (FCoE) ports. If your systemhas an optionally installed Fibre Channel and FCoE adapter for host andexternal storage attachment, ensure that these ports are accessible.

– The nodes and the enclosures themselves. Access is required to the hardwarefor servicing and for safely removing and replacing components by using twoor more people.

Procedure

To install the cables, complete the following steps.1. Using the supplied SAS cables, connect the top node ▌2▐ to the expansion

enclosures, as shown in Figure 51 on page 48.a. Connect SAS port 1 of the top node ▌2▐ to SAS port 1 of the left canister in

the first expansion enclosure ▌1▐.b. Connect SAS port 3 of the top node ▌2▐ to SAS port 1 of the left canister in

the second expansion enclosure ▌4▐.


2. Using the supplied SAS cables, connect the second node ▌3▐ to the expansionenclosures, as shown in Figure 51.a. Connect SAS port 1 of the bottom node ▌3▐ to SAS port 1 of the right

canister in the first expansion enclosure ▌1▐.b. Connect SAS port 3 of the bottom node ▌3▐ to SAS port 1 of the right

canister in second expansion enclosure ▌4▐.3. If more I/O groups are configured, repeat the cabling procedure from each of

the two nodes within the I/O group to the installed expansion enclosures forthat I/O group. The system supports up to four I/O groups with a total ofeight expansion enclosures per system.

Initializing the system by using the technician portTo initialize a new system, you must connect a personal computer to the technicianport on the rear of a node and run the initialization tool. This node becomes theconfiguration node and provides access to the management GUI. Access themanagement GUI by using the management IP address through your IP networkor through the technician port. Use the management GUI to add each candidatenode to the system.

Chapter 4. Initializing the SAN Volume Controller 2145-DH8 system 51

Before you begin

Important: Do not use the initialization tool on a node if any other node in thesystem is already active. For example, a node status LED is solid on any node ofthe system.

You require the following items:v A personal computer with an Ethernet port that supports Dynamic Host

Configuration Protocol (DHCP)v A supported browser that is installed on the personal computerv An Ethernet cable to connect the personal computer to the technician port

Attention: Do not connect the technician port to a switch. If a switch is detected,the technician port connection might shut down, causing a 746 node error.

Procedure

To initialize the system, complete the following steps.1. Ensure that the nodes and switches of the system are powered on. (Refer to

“Powering on and powering off the clustered system” in the SAN VolumeController IBM Knowledge Center.)

2. Configure an Ethernet port on the personal computer to enable Dynamic HostConfiguration Protocol (DHCP) configuration of its IP address and DNSsettings.

3. Starting from the left at the rear of the node, locate the fourth Ethernet port tothe right, which is the technician port. Figure 52 shows the rear of the SANVolume Controller node, where ▌1▐ is the technician port.

4. Connect an Ethernet cable between the port of the personal computer that isconfigured in step 2 and the technician port. A few moments after theconnection is made, the node uses DHCP to configure IP and DNS settings ofthe personal computer. If you do not have DHCP, configure static IPv4 address192.168.0.2, mask to 255.255.255.0, gateway to 192.168.0.1, and DNS to192.168.0.1.

5. After the Ethernet port of the personal computer is connected, open asupported browser and browse to address http://install. (If you do not haveDCHP, open a supported browser and go to the following static IP address192.168.0.1.) The browser is automatically directed to the initialization tool.

Note: If the system cannot be initialized, you are directed to the serviceassistant interface.

6. Follow the instructions that are presented by the initialization tool to configurethe system with a name and management IP address.

7. If you experience a problem during the process due to a change in systemstates, wait 5 - 10 seconds. Then, either reopen the SSH connection or reloadthe service assistant.

8. After you complete the initialization process, disconnect the cable between thepersonal computer and the technician port.

What to do next

The system management GUI can now be reached by opening a supported webbrowser and pointing it to http://management_IP_address. Use the managementGUI to add each candidate node to the system. Then, it is best to use themanagement GUI to set the service IP address for each node now. Ensure that thesystem is disconnected from the technician port.

Adding nodes to an existing clustered systemBefore you add a node to an existing system, consider this high-level overview ofthe requirements and tasks involved.

Before you begin

This task requires that the following conditions are met:v All nodes that are configured in the system are present. Nodes must be installed

in pairs. Each pair of nodes is an I/O group.v All errors in the system event log are fixed.v All managed disks (MDisks) are online.v A node with only Fibre Channel over Ethernet (FCoE) ports (all FCoE ports)

connected to the switch and properly zoned can also be added to an I/O group.

About this task

Table 9 lists the models and software version requirements for nodes.

Note: The steps in the following procedure refer to uninterruptible power supplyunits. SAN Volume Controller 2145-DH8 does not have an external uninterruptiblepower supply unit. This system has battery modules in its front panel instead.

Procedure1. Install the SAN Volume Controller nodes, and if applicable the uninterruptible

power supply units, in the rack.2. Connect the SAN Volume Controller nodes to the LAN.3. Connect the SAN Volume Controller nodes to the SAN fabric.

Chapter 4. Initializing the SAN Volume Controller 2145-DH8 system 53

4. Power on the SAN Volume Controller nodes and, if applicable, theuninterruptible power supply units.

5. Zone the SAN Volume Controller node ports in the existing SAN VolumeController zone. The SAN Volume Controller zone exists in each fabric withonly node ports.

6. Zone the SAN Volume Controller node ports in the existing SAN VolumeController and storage zone. A storage zone contains all of the SAN VolumeController node ports and storage system ports that are in the fabric and usedto access the physical disks.

7. For each storage system that is used with the SAN Volume Controller clusteredsystem, use the system management application to map the LUNs that arecurrently used by the clustered system to all of the WWPNs of the SANVolume Controller nodes that you want to add. The SAN Volume Controllernodes must recognize the same LUNs that the existing nodes in the clusteredsystem can recognize before they can be added. If the SAN Volume Controllernodes cannot recognize the same LUNs, the storage system is markeddegraded.

8. Add the SAN Volume Controller nodes to the clustered system.9. Check the status of the storage systems and MDisks to ensure that status is not

marked degraded. If the status is degraded, a configuration problem must beresolved before you can do any further system configuration task. If theproblem cannot be resolved, remove the newly added SAN Volume Controllernodes from the clustered system and contact the IBM Support Center forassistance.

What to do next

For specific instructions about adding a new node or adding a replacement node toa clustered system, see the information about adding nodes to a clustered systemin the IBM SAN Volume Controller Troubleshooting Guide.
